Many biological processes involve one dimensional diffusion over a correlated inhomogeneous energy landscape with a correlation length $ξ_c$. Typical examples are specific protein target location on DNA, nucleosome repositioning, or DNA translocation through a nanopore, in all cases with $ξ_c\approx$ 10 nm. We investigate such transport processes by the mean first passage time (MFPT) formalism, and find diffusion times which exhibit strong sample to sample fluctuations. For a a displacement $N$, the ...

A number of vital biological processes rely on fast and precise recognition of a specific DNA sequence (site) by a protein. How can a protein find its site on a long DNA molecule among 106–109 decoy sites? Here, we present our recent studies of the protein–DNA search problem. Seminal biophysical works suggested that the protein–DNA search is facilitated by 1D diffusion of the protein along DNA (sliding). We present a simple framework to calculate the mean search time and focus on several new aspects ...

The article analyzes the development of the Eurasian Economic Union (EAEU) before, during and after the COVID-19 pandemic through the lens of the so-called integration dilemma, when one state perceives its neighbors' integration into an economic alliance as a threat to its own security or prosperity.The authors consider the processes of interstate and supranational adaptation, as well as the adaptation of the basic model of integration to the existing practices of interaction as part of the project ...

Autophagy genes' expression is upregulated in visceral fat in human obesity, associating with obesity-related cardio-metabolic risk. E2F1 (E2F transcription factor 1) was shown in cancer cells to transcriptionally regulate autophagy. We hypothesize that E2F1 regulates adipocyte autophagy in obesity, associating with endocrine/metabolic dysfunction, thereby, representing non-cell-cycle function of this transcription factor. E2F1 protein (N=69) and mRNA (N=437) were elevated in visceral fat of obese ...

Abstract Unexpectedly, a post-translational modification of DNA-binding proteins, initiating the cell response to single-strand DNA damage, was also required for long-term memory acquisition in a variety of learning paradigms. Our findings disclose a molecular mechanism based on PARP1-Erk synergism, which may underlie this phenomenon. A stimulation induced PARP1 binding to phosphorylated Erk2 in the chromatin of cerebral neurons caused Erk-induced PARP1 activation, rendering transcription factors ...
